Delphi 12-14-7-539-171 Camshaft Position Sensor

The Delphi 12-14-7-539-171 is a direct-fit camshaft position sensor (CMP sensor) engineered to OEM specifications for precise camshaft timing detection. Delphi, a trusted global supplier to original equipment manufacturers, delivers this sensor with the same fit, form, and function as the factory-installed component it replaces.

The camshaft position sensor monitors the rotational position of the camshaft and sends this data to the engine control module (ECM). This signal is critical for accurate fuel injection timing, ignition timing, and variable valve timing (VVT) system operation. A failed or failing CMP sensor can trigger a check engine light (MIL), cause rough idle, hard starting, misfires, or poor fuel economy.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Manufactured by Delphi, a Tier-1 original equipment supplier
• Precision Hall-effect sensing element for accurate camshaft position detection
• Designed to meet or exceed original equipment specifications
• Helps restore proper fuel injection and ignition timing
• Corrosion-resistant housing for long-term durability
• Plug-and-play connector matches factory wiring harness

OEM Reference Part Number: 12-14-7-539-171 (also referenced as 12147539171). This Delphi camshaft position sensor is the reliable, cost-effective solution for restoring accurate engine management performance.
